### PPR1 TODO
* fix usb - check latest tinyusb
* Test GPS - try pulsing reset
* fix usb - I think the problem is VBUS in HW
* Test GPS - try pulsing reset - no joy. R19 is the resistor on the TX path from GPS to CPU
R17 is the resistor for V_BK GPS power (measured 3V - ok!), R20 is the resistor for the RX path from CPU to GPS. R18 for RESET (it is low and GPS reset is high - ok!)
* V_BK for the GPS should probably be supplied from something always on
* use S113 soft device 7.2.0
* properly test charge controller config and read battery/charge status
* fix bluetooth
* fix LCD max contrast (currently too high, needs to be about 40?)
